JSON returned from php...

JSON returned from php...

Every parse example I have seen on the internet is the well formed;
 
jQuery.parseJSON( ' {"sid":"123455","client_id":"1","last_name":"Anderson","first_name":"Alan","institution_id":"1"} ');
 
 
What is the easy way to get from this; 

{"posts":[{"post":{"sid":"123455","client_id":"1","last_name":"Anderson","first_name":"Alan","institution_id":"1"}},

{"post":{"sid":"b","client_id":"4","last_name":"b","first_name":"b","institution_id":"1"}}]}
 
to 'well formed' so that  jQuery.parseJSON( data )  will work?
 
Thank You for your time.
